BAIL JOINT.

Appneation meanugusfas, 192e. serial yNo. 130,923.

This invention relates to rail joints in which the opposing ends'ot the rails overlapand have their adjacent faces beveled/so the tread surface of the rail at the joint 1s the same Width as the rest of each rail; and the object is to provide a safer joint than that usually employed and one in which the passing Wheels Will pound less over 'openings due to contraction ot' the rails.

A further object is to provide a rail-joint with a positive shoulder-stop between the joined ends, such as can be easily made .on the job by section men, and reduce the s1ze of fish-plates and the number of bolts ordinarily required to join rail-ends as they are now connected.

The invention is fully shown in the accompanying drawing, in which* Fig. 1, isa side elevation of the ends of rails when shaped and brought together to form a joint embodying my invention.

Fig. 2, isza cross section on the hne 2 2 of 'Fig.l. y

Fig. 3, is a top plan view ot the joined Fig. 4, is an` underside plan view of the same parts shown in Fig. 3.

The numerals 5 and 6 designate two rails having their adjacent ends beveled on their inner surfaces on a diagonal line a-b eX- vtending entirely through the tread 7 andl web 8, and through the base 9 from one edge at a, to the joint b, at an appreciable distance in from the opposite edge of the base, and thence at right angles to the base edges at c in the edge ofy the base nearest to b. Contacting shoulders 10 and 11, are thus formed in base 9 Which stop the movement ot the rail-ends toward each other.

The above described bevels and shoulders ycan be easily formed by section men in making repairs by sawing a rail in two, beginning at (L and sawing diagonally to and then from c, on the other side from the starting point a, in at right angles to intersection with the diagonal kertl at b.

A pair ot' fislrplates 12 and 13, are bolted, one on each side ot the web 8, by bolts 14 and 15. The bolt-hole; 16 in the fish-plates are here shown as elongated to allow for expansion and contractiontof the rails, under varying temperatures, but the elongations may be made, instead, in the holes in the rai s-through which the bolts pass.

To counteract any tendency toward depression of the rails at the joints caused by the pounding ofthe car Wheels,I prefer to provide a bridge-plate 17 to rest upon adjacent ties 18betWeen the ties and the railbase under the rail-joint. v

My improved joint as above described and as shown in the drawing-reduces the wear on passing car Wheels and the Wear of the Wheels on the rail joints; and the clicking sound incident to Wheels passing over straight joints of ordinary construction isV avoided because the load-shift from one rail to the other is gradual instead of abrupt.

j Having thus described my invention, what I claim as new and Wish to secure by Letters Patent,l is- 1. A rail-joint comprising rail sections having the adjacent ends reversely beveled and lapped, the bevel on one side only of the rail terminating in portions at an angle to the bevel forming shoulders adapted to contact with each other and limit the longitudinal movement of the rail sections toward each other.

2. -A rail-'joint comprising nrail sections having the adjacent ends reversely beveled.

and lapped, the bevel on one side only of the rail terminating in portions at an angle to the bevel forming shoulders adapted to contact with each other and limit the longitudinalmovement of the rail sections toward each other, and a pair of fish plates between which the rail joint is bolted.

3. A. rail-joint comprising rail sections having the adjacent ends reversely beveled` and lapped, the bevel -on one side only of the rail terminating in portions at an angle to the bevel' forming shoulders adapted to contact with each other and limit the longitudinal movement of the rail sections toward each other, a pair ottish plates between which the rail joint is bolted and a bridge plate bridging a plurality ot' ties, upon which plate the rail-joint is supported.

1n testimony whereof I affix my signature.
